While doing a demonstration of the reporting capabilities of Scrutinizer last week, I had a customer ask, “How can I monitor Netflix traffic?”
There are a couple of ways that this can be done.
If you have Cisco routers, and are running IOS 15.1 or higher, there is an option to enable NBAR. Using Flexible NetFlow, we create a user defined flow template by adding the collect NBAR application option parameters to the flow record. Then it is just a matter of selecting the NBAR report filters available in Scrutinizer.
But I would like to show you a way to use a template option to capture and pass URL’s. We will be using nProbe to capture traffic from an interface on a device and export IPFIX templates to Scrutinizer.
The set up of nProbe is a simple process of using command line options to configure the template and create and start a nProbe service.
Once we see the device and interfaces in Scrutinizer, it is just a matter of adding filters to the report to isolate the Netflix traffic.
